Proposed EPA Plan Would Cut Emissions From Power Plants By 30%

On June 2, the EPA announced the Clean Power Plan. Under the Clean Air Act and President Obama's Climate Action Plan, the proposed plan would cut carbon pollution from existing power plants, the largest source of greenhouse gas emissions in the U.S.

Switch to Natural Gas Power Plants Reduces Carbon Dioxide Emissions

Power plants that use natural gas release far less of the greenhouse gas carbon dioxide than coal-fired power plants, according to a new study from CIRES and NOAA scientists.

In this activity, students conduct a life cycle assessment of energy used and produced in ethanol production, and a life cycle assessment of carbon dioxide used and produced in ethanol production.

This video features a short animated sequence that illustrates the difference between young and old carbon released into the atmosphere from the consumption of food (young carbon) and the burning of fossil fuels (old carbon).

This humorous video suggests what might happen if a weather forecaster reported the weather in the context of climate change. There is a sharp contrast between the anchor focusing on short-term local concerns and the weather forecaster describing what is happening on a long-term global basis.

This short video describes the Hestia project - a software tool and data model that provide visualizations of localized CO2 emissions from residential, commercial, and vehicle levels, as well as day versus night comparisons, in the city of Indianapolis.

Students consider why the observed atmospheric CO2 increase rate is only ~60% of the CO2 loading rate due to fossil fuel combustion. They develop a box-model to simulate the atmospheric CO2 increase during the industrial era and compare it to the historic observations of atmospheric CO2 concentrations. The model is then used to forecast future concentrations of atmospheric CO2 during the next century.

This straightforward calculator provides conversions from one unit of energy to the equivalent amount of CO2 emission expected from using that amount.

In this free webinar, speakers will discuss mitigation of extreme weather events resulting from climate change.

Air Quality

Air pollution has significant health, economic, and ecological consequences.  This NOAA fact sheet discusses the gaseous and particle pollutants found in the air we breathe, and how they impact air quality.
